Version 0.3.5 of JayCache Util - a set of java classes for geodetic calculations - has been published.
As a by-product, an applet (http://jaycache.sourceforge.net/applet.php) which uses the library has been created. The applet is able to calculate the distance/azimuth between two coordinate, project waypoints, etc.
JayCache is going to be a geocaching tool written in Java. JayCache Util and the applet is only a small part of the whole project, but both are quite usable right now.
